F(x) = x+4 g(x) = 3x^2 - 7. Find (f•g)(x) a. (F•g)(x) = 3x^3 + 2

b. (F•g)(x) = 3x^3 - 28

c. (F•g)(x) = 3x^3 + 12x^2 + 7x +28

d. (F•g)(x) = 3x^3 + 12x^2 - 7x - 28

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

correct answer is b. 27/8
